Mainframe, MVS and zOS Discussion

With this post, I am starting a series on the extraordinary relationship between hardware and the software that runs upon it. I’m a software engineer.

But what software engineer doesn’t have a healthy respect for the hardware? Respect is one thing, but understanding it is another.
